This patch causes the --cvs-exclude option to prefix the names listed
in each dir's CVS/Entries file as per-dir includes before the dir's list
of excludes taken from the .cvsignore file.

To use this patch, run these commands for a successful build:

    patch -p1 <patches/cvs-entries.diff
    ./configure                                 (optional if already run)
    make
